Did some work over the weekend.Here's what I found.The "D3" line is loaded down to about 2 volts.All the other Data lines are reading 4.8- 5 volts.Pulled the PROMS, didn't make any difference.How many, and what I.C.s can I remove in what sequence without damaging the components to isolate the problem?
